Good morning, I have a '51 model A that had sat for a few decades before I got it. After doing what it needed to get running, I decided to tackle
the job of replacing the exhaust manifold. It was cracked on the LF corner, the only hole that's not solid all the way down. I got the manifold
off, found some minor pitting around exhaust ports(no surprise there), but the ex ports are about .020" lower than the intake ports. I've been
filing on it and it's got a good enough surface that I believe it'll seal up. The engine makes 60 lbs cranking compression on both cylinders,
doesn't blow blue smoke, doesn't overheat.
My dilemma, I own a cylinder head shop and could do anything the head needs, including milling the HG and manifold surfaces. What might I discover
if I remove the head besides pitted cylinder walls, possibly broken head studs, pitted deck, etc? I really don't want to get into the bottom end to
do cylinder work if I find something I don't like.
It's not a show tractor or even a restoration, just a project I took on after my great uncle died and left this in his back yard.
Thanks
